Drink Botanicals Ireland makes garnishes and syrups for cocktails.
The US is a vital market for the company, accounting for more than 40% of sales last year.
Founder and CEO Laura McCarthy said she is worried about the impact of any tariffs that might be introduced by Donald Trump.
"We're scared as a small Irish business to see what the implications are going to be if tariffs are going to be slapped on," Ms McCarthy said.
"I think the uncertainty and the unknown is scaring SMEs in Ireland."
"We rely heavily on the US market but with Trump coming into power, no one knows what way it is going to go."
"If he does impose tariffs, we could lose our competitive advantage and it could have a knock-on effect for a lot of businesses in Ireland."
Drink Botanicals Ireland is the third best seller in its category on Amazon US.
"We would see it as a critical market where there are opportunities for further growth but it is tricky now to see what's going to happen with Donald Trump coming into power," Ms McCarthy said.
Aside from tariffs, the bigger concern for Ireland as a country would be any measures introduced by the Trump administration that would damage the bumper corporate tax receipts we earn from US multinationals.
The incoming US president could lower the American corporate tax rate to match Ireland's, or could introduce further incentives to encourage companies to move profits and intellectual property back to the US.
Professor of Political Economy at University College Dublin Aidan Regan said we should be worried about what is to come.
"Ireland has benefited from globalisation and the free flow of capital, jobs and investment," Professor Regan said.
"Anything that negatively affects that, or reverses it, given how closely connected we are in terms of trade, is going to negatively affect the Irish economy."
"So I think we should be very worried about Donald Trump's economic policies," he added.
